David Wright from ABC News fills in for Madeleine this week. White abalone might be tasty, but they've faced dwindling population numbers since the 90's, and now could soon be extinct. Marine Biologist Pat Krug talks with David about the future of the species. Tax breaks? Economic stimulus? How do you fix the economy? Most ideas come from Washington or Wall Street, but what if solutions came from Main Street? David talks to reporter David Brancaccio, who traveled throughout the U.S. to see how innovative companies are restoring jobs for his new documentary, "Fixing the Future." Santa Monica has long banned the use of noisy leaf blowers, but that doesn't mean that the practice of using them has stopped. Reporter Jennifer Sharpe has the second part of her story. And Ann Powers is back to review two new albums from The Very Best and Frank Ocean.
